Troubleshoot your Wired Connections

Try this first: Make sure your computer is connected to your gateway (with an Ethernet cord, wirelessly or both) and that your connection is active, as indicated by the green status lights on your gateway modem. Reboot both your computer and gateway.

Before moving on to the troubleshooting steps give these quick tips a try:

Clear Cache - while cookies and cache help make your web surfing experience a little better and quicker, sometimes things can get bogged down a bot. One of the most common ways to freshen up the browser is by clearing the browsing data, such as cookies, cache and history. Here is how it’s done:

Launch your Web browser
Press Ctrl+Shift+Delete
A browsing history menu will display. Select the type of items you’d like to clear.
Select the Delete or Clear button, depending on your browser type.
Close and re-start your browser.
The browsing data screens look like this, depending on your browser (pictured from left to right: FireFox, Internet Explorer and Chrome):

Virus/Spyware Scans - Run virus and spyware scans regularly

Number of Devices - If you also use Wi-Fi, limit the number of devices (computers, gaming systems, mobile phones, tablets, etc) that share your internet connection at the same time

Check Status Lights

Each modem or gateway status light has a specific meaning about your current internet connection. Make sure it is turned ON and that your Power, Broadband, and Service lights on your gateway are green. If your lights are not green, you may have a problem getting a signal or your gateway may be having a problem. Your modem or may vary based on model and manufacturer.

Check Connections

Check that all cables and wires (power cords, phone lines, and Ethernet cables) are securely plugged into your gateway and computer and the power is ON. The gateway should not be plugged into a surge protector. A typical set-up looks like this, but your equipment may vary.

Learn more about modem or gateway setup and installation for your specific device.

Check Filters

If you have traditional phone service or telephone equipment plugged into your telephone jack, you need a filter to receive the AT&T broadband signal. Depending on how many devices you have, you may need additional filters.

Important Note - If you do not have traditional phone service or telephone equipment plugged into your telephone line (e.g., phones, fax machines, answering machines), you can skip to the next step

Incorrect filter configuration can interfere with your connection, so make sure filters are installed on all phone jacks that have telephone devices connected (e.g., phones, fax machines, answering machines). Verify the modem or gateway is plugged into the DSL/HPNA side of the filter, and the phone line is plugged into the phone jack side of the filter.

To check if the line filter is working on Dual Port filters, plug in your phone and listen for a dial tone. If there is static on the line, you may need a new filter. Learn more about installing line filters.

Reset your Computer and Modem

Shut down your computer and power cycle your modem or gateway by unplugging the power cord on the unit from the wall outlet, and then wait two minutes before plugging your gateway back in.
Watch for the lights to restore on your Gateway. If your Power, Broadband, and Service lights on your gateway are green, go onto the next step. If your LED lights are not green, you may have a problem getting a signal or your gateway may be having a problem.
Turn your computer back on.
After the Power, Broadband, and Service lights on your modem or gateway turn green, check your Internet connection. If it has not been restored, proceed to the next step.

Check Software Settings

Reset your browser by launching your Web browser and clearing both the browser cache and cookies. This will free up space on your computer or mobile device and permit more temporary storage of Web content. Your browser's support site can instruct you on how to do this.
Check your browser's connection settings to make sure there are no proxies or filters in place that could interfere with your ability to browse the Web or check email. Your browser's support site can instruct you on how to do this.
Make sure you're only running one firewall. In addition, you may want to disable your firewall temporarily to determine if the firewall is the cause of your problem.
Run your anti-virus and anti-spyware software. Malicious software can deplete your computer's system resources. You can learn more about the AT&T Internet Security Suite powered by McAfee.

Try rebooting the modem or a different Ethernet port. This topic is 8 years old plus it's more of a information link, closing to further posting, please open your own topic if further information is needed.
